Centre Stage Audio
The Vanishing Series 255C-RT is the centrepiece of a world-class stealth home theatre. Paintable to match any décor, this in-wall centre channel speaker blends in perfectly with its surroundings. Anchoring all the action without attracting attention, the 255C-RT ensures all you see is the screen, and all you hear is dynamic, crystal clear sound.
Sheer-Grille™
The unique, wafer-thin grille is magnetically secured to deliver nearly transparent, ultra-small perfs and dynamic, unimpeded sound.
Power Port®
Patented bass venting design smoothly transitions air flow, eliminating turbulence and distortion, for deeper, more efficient bass impact.
Timbre-Matching
Compatible with Polk Audio RTi speakers for seamless blending between traditional and built-in speaker systems.
Reflective Room Compensation
Lower tweeter levels offset reflective surfaces, cutting the level in the exact 4-5kHz band where reflectivity destroys sound quality.
Distance Toggle
Crossover adjustments flatten response bumps caused by nearby walls, reducing “boominess” for more lifelike sound from any position.
Simple Setup
Perfect Fit templates, a precision flange, available pre-construction brackets and the patented Rotating Cam system ensure secure, vibration-free installation.
